At FOW, we use multiple specialty machines to work the 'big thing' such as the outlook of our molds, and the 'small things' like rejector pin holes etc,. Our equipments include:

The choice of mold material is crucial as it affects the mold's durability, performance, and quality of the parts produced. Hardened steel molds, for example, are highly durable and can produce high-quality parts with excellent surface finish, but they are also expensive and take longer to manufacture. Aluminum molds, on the other hand, are less expensive and quicker to produce, but they may need to be more durable and capable of producing parts with the same level of detail or surface finish.

Properties: Polystyrene is a rigid, brittle plastic often used in disposable products due to its low cost. It is available in both a general-purpose form and a high-impact form that is more durable.

Properties: Thermoplastic polyurethane is a versatile plastic that offers high elasticity and transparency, as well as resistance to oil, grease, and abrasion.

The cost of plastic injection molding comprises several factors, including mold cost, materials cost, injection cost, and costs associated with quality control and packing.

Despite its challenges, injection moulding is a versatile and efficient manufacturing process. It allows for producing various parts in various materials and colors, from simple to complex. With careful planning and consideration, it can be a cost-effective solution for high-volume production.

We know the importance of varied injection molding options in plastic injection mold makinhg. In order for products to be mass produced swiftly, industries need good quality molds.Which is why we offer multiple mold making techniques.

The most common method. Thermoplastic resin pellets are fed into the injection moulding machine, melted, injected into a mould, cooled, and ejected as a solid part. Used for high-volume production of parts.

The materials cost includes the cost of the plastic resin used in the molding process. The cost of the resin can vary depending on the type of plastic used, the market price of the plastic, and the quantity required.

2. Part Design Restrictions: While injection molding can handle complex part designs, there are some restrictions. For example, parts with very thin walls or complex undercuts may be difficult or impossible to produce.

Properties: Acrylic, also known as PMMA, is a clear, rigid plastic that resembles glass. It has excellent weather resistance, is stable over various temperatures, and resists UV light and impact.

When designing a multiple-cavity mold, it's essential to ensure that the plastic flows evenly into all cavities. This requires careful design of the runners and gates and may also require using a hot runner injection system to maintain the plastic's temperature.

Cooling: The cooling process begins once the plastic has been injected and dwelled in the mold. The cooling process is crucial as it allows the plastic to solidify and take the shape of the mold.

The quantity of parts to be produced is another vital consideration. Injection moulding is most cost-effective for high-volume production runs, where the initial costs can be spread over many parts. For low-volume production, other manufacturing methods may be more cost-effective.

Plastic injection molding is Immould’s bread and butter. This technique allows us to makes some of the most sophisticated and robust molds in the world.

The injection unit consists of the hopper, barrel, heaters, reciprocating screw, and nozzle. The hopper is a large container where the raw plastic pellets are fed. The barrel contains the reciprocating screw and has heaters jacketed on its periphery. The heaters provide thermal energy to melt the plastic pellets to their molten, dense state. The reciprocating screw pushes the plastic through the barrel's length by rotating and sliding axially. The nozzle introduces the molten plastic to the mold cavities.

Removal of Products: The final step in the injection molding process is removing the cooled plastic part from the mold. The part is typically ejected from the mold using ejector pins.

Applications: TPEs are often used in applications that require flexibility and durability, such as seals, gaskets, and soft-touch grips.

Insert molding service involves injecting plastic around an insert made of a different material. The insert can be a simple object, like a metal rod, or a complex assembly of multiple parts. The resulting product is a single piece with the insert encapsulated by the plastic. This process is often used to create parts that combine metal's strength with plastic's flexibility and versatility.

The mold must also be designed to allow for efficient cooling. This is typically achieved by incorporating cooling channels into the mold design, through which a cooling fluid can circulate to remove heat from the plastic.

One of our greatest advantages as a mould making company, is our injection mold factory. Not only is it manned by a highly trained crew of workers, it is also equipped with a wire cutting machine, lathing machine, Engraving machine, and a CNC machine. These great examples of high-powered machinery allows us to fulfill all our client’s requests.

Properties: Polyethylene is a lightweight, durable plastic with excellent chemical resistance. It's available in various densities, with high-density polyethylene (HDPE) being more substantial and more rigid and low-density polyethylene (LDPE) being more flexible.

A secondary plastic is an injection molded over a primary plastic part already in the mould. Creates a two-material part with an inner core and outer layer. Used for grips, buttons, seals, etc.

In Neway's rapid molding service, rapid molds can be manufactured within 24 hours, and 100% replicas of injection molded parts can be achieved. Although rapid molds are cheap, their life is concise, and usually, only 50 or fewer prototypes can be produced. Rapid tooling technology is suitable for projects that require 100% replicas of the final injection molded product before opening the injection mold.

During each process of mold-making, CMM coordinate measuring machine is used to inspect dimensions. Only when the dimension of each part is confirmed will it enter the next step.

Properties: Polycarbonate is a robust and rugged material with high impact resistance. It also has excellent transparency and can be molded into complex shapes.

The principal advantage of injection molding service is the ability to scale production en masse. Once the initial costs have been paid, the price per unit during injection molded manufacturing is meager. The price also tends to drop drastically as more parts are produced.

3. Limited Material Choices: While many materials can be used in injection molding, not all materials are suitable. Some materials may not have the necessary flow characteristics or may degrade at the temperatures used in the process.

The plastic mold design is a complex process that requires a deep understanding of the plastic material being used, the desired shape and features of the part, and the specific requirements of the molding process. The mold must be designed to allow for easy ejection of the part after it has cooled and solidified and to withstand the high pressures and temperatures involved in the process.

Quality control (QC) and packing are significant cost factors in plastic injection molding. QC involves inspecting the parts to ensure they meet the required specifications, while packing involves preparing the parts for shipment. These processes require time and labor, which add to the overall cost.

1. High Production Speed: Injection molding is a fast process for high production rates. Once the initial setup is complete, the process can produce thousands of parts in a short amount of time.

Material selection plays a crucial role in the success of a plastic injection molding project. The chosen material must meet the functional and aesthetic requirements of the part, be compatible with the molding process, and fit within the project's budget. A thorough understanding of the properties and advantages of different materials can help make an informed material selection.

The financial aspects of a project are always a significant consideration. This includes the cost of the injection moulding machine, the molds, the materials, and the labor. It's essential to consider the project's total cost, including the initial investment and the ongoing production costs.

Pressurized gas (typically nitrogen) is injected into the molten plastic to create hollow channels and cavities in the part, reducing sink marks and warpage. Used for large, hollow parts.

The injection unit is where the raw plastic pellets are melted and delivered to the mold. It is responsible for supplying molten plastic to fill the mold cavities, applying heat to melt and homogenize the plastic pellets before injecting them into the mold, and applying sufficient injection pressure and speed to push the molten plastic and fill the mold cavities.

The construction of a mold must be precise and robust to withstand the high pressures and temperatures of the injection molding process. The mold must be made from a material that can resist the corrosive effects of the plastic and the wear and tear of repeated cycles. Common mold materials include hardened steel, pre-hardened steel, aluminum, and beryllium-copper alloy.

An injection molding machine is a complex machinery comprising various components that work harmoniously to create plastic parts. The machine primarily consists of two main parts: the clamping unit and the injection unit.

The sprue is the channel through which the molten plastic enters the mold from the injection machine. The runners are the channels that distribute the plastic from the sprue to the cavities. The cavities are the hollow spaces in the mold that form the shape of the part.

Dwelling: After the injection, the molten plastic can dwell inside the cavities. The injection pressure is replaced by the holding pressure in this step to compact the plastic and ensure it fills every mold corner.

Medical Industry: Injection moulding is used extensively in the medical industry to produce a wide range of products, from surgical instruments to implantable components. The process allows for the production of exact and consistent parts, which is crucial in medical applications.

3. High Efficiency: Injection molding is a highly efficient process with a low scrap rate. The process allows for the use of regrind, further reducing waste.
